Steel production is likely to take up a large portion of our future carbon budget. Capturing CO₂ from coal-based production won’t solve the problem. Technologies that rely on renewables are more effective, but not enough to get to net zero.

Imagine we could do what green plants can do: photosynthesis. Then we could satisfy our enormous energy needs with deep-green hydrogen and climate-neutral biodiesel. Scientists have been working on this for decades. Chemist Chengyu Liu will receive his doctorate on 8 June for yet another step that brings…

She received the prize for her thesis entitled 'Accounting for Accountability: Europol between Protecting Personal Data and Fostering Innovative Artificial Intelligence for Law Enforcement…

Using biomethane to produce ammonia, a crucial chemical in agriculture, could drastically reduce the climate impact of the process. In a study published in One Earth, researcher Robert Istrate shows it’s even possible to make ammonia production net-zero or carbon negative.

Studying surfaces of solid materials: it may not seem relevant to energy consumption, but it is. Marcel Rost studies how platinum electrodes wear out. Those electrodes are a crucial component in the fuel cells of hydrogen-powered cars. ‘We need to make the switch from fossil fuel energy to hydrogen.…

Wat kun je als burger doen wanneer de overheid je persoonsgegevens gebruikt en daarmee besluiten neemt waar je het niet mee eens bent? Fatma Çapkurt promoveerde op een onderzoek hiernaar. Burgers moeten verwerking van hun gegevens beter kunnen beoordelen.

Developing safer alternatives to harmful PFAS filters and seeking new enzymes for medical applications. Two projects with Leiden researchers have been awarded funding through the Dutch Research Council's (NWO) Open Technology programme.

In the Netherlands it is now possible to visit non-essential shops if you make an appointment beforehand. But when you book an appointment you have to provide a lot of personal data. Are shops allowed to ask you for all this data and what happens to it?

What reduces the likelihood of children being taken into care? Anouk Goemans calls for data-driven systems, alongside attention to the stories behind the numbers.

More than twenty years ago, Hurricane Katrina devastated the southern United States with nearly 1,400 deaths. Due to climate change, the lessons from this disaster are more relevant than ever, but the Trump administration seems to be ignoring them by cutting funding for disaster management. Anthropologist…

Regardless of whether you work at a desk or in a lab, all workplaces have their risks. As your employer, the University aims to create a healthy workplace and to limit possible health risks. Here you will find the main risks and measures that we take to reduce them.

Researchers from Leiden University and Solid Sustainability Research have published a new study in PLOS Climate on the links between Dutch universities and the tobacco industry. Through this work, they aim to contribute to ongoing discussions about ties to the fossil fuel sector.

In this commentary, Sabine Witting, Assistant Professor at eLaw, provides a comprehensive analysis of the Second Optional Protocol to the United Nations Convention on the Rights of the Child on the sale of children, child prostitution and child pornography.

Dr Gianclaudio Malgieri, Associate Professor at eLaw – Center for Law and Digital Technologies, has been appointed Co-Rapporteur for a new joint project of the European Law Institute (ELI) and the American Law Institute (ALI): 'Principles for the Governance of Biometrics'. The project aims to formulate…

Recent developments in AI mean nobody is anonymous nowadays. The search engine PimEyes can find any photo of anyone that’s ever been placed online. No more Tinder Swindlers… or personal privacy. Everyone’s findable now. But is that even allowed?
